ixgbe: Don't allow user buffer count to exceed 256 If the user buffer count was 256 the shift would place a 1 in the offset region leading to errors. It also overwrites the uers buffer list. This patch makes sure that at most 256 user buffers are allowed for DDP and the buffer count is masked properly such that it doesn't overwrite the offset when shifting the bits.
